Title: Improvements relating to the mounting of vibrating reeds, more particularly for use in connection with electromagnetic gramophone pick-ups, loud speakers and the like
IPC: H04R11/08
Filed: 1930-05-15
Abstract: 355,227. Sound recording and reproducing devices. WILSON, P., 48, Clarendon Road, Putney, London. May 15, 1930, No. 15018. [Class 40 (iv).] In electromagnetic sound recording and reproducing instruments, and particularly gramophone pick-ups, an armature is mounted so as to vibrate towards and away from one or more magnet poles so as to vary the length of the air gap between the armature and the poles, and a restoring force is set up as the armature vibrates, due to the magnetic action between the armature and two or more additional poles, which may, for example, be so placed that the vibrating armature sweeps past them so as to vary the overlapping area. In the construction shown in Figs. 1 and 2, and illustrated diagrammatically in Fig. 6, a U-shaped permanent magnet 1 has one limb in contact with an iron plate 2, which is fixed to a brass plate 3 abutting against the lower limb. The main poles 4 are screwed into the iron plate 2 and located in holes in the brass plate 3, and are surrounded by the speech coils 5. The additional poles 6 make contact with the lower limb of the magnet 1, and are fixed by screws 7 to the plate 3, their pole faces 8 being opposite lateral limbs 15 on an armature 9, which is pressed by a spring against steel balls, knife edges, &c. so as to vibrate about an axis x, Fig. 6, so as to move towards and away from the poles 4, the end faces of the lateral limbs 15 sweeping across the pole faces 8 to vary the overlapping area. The gaps between the pole faces 8 and the ends of the limbs 15 may be adjusted by turning the polepieces 6 about the screws 7. The main poles 4 may consist of tubes provided with plungers to increase the magnetic restoring force in the manner described in Specification 321,688, [Class 40 (iv), Telephones &c.], and mechanical damping- means, such as rubber pads, may also be employed. The armature may be made partly of magnetic and partly of non-magnetic material. In another form, Fig. 10 (not shown), one end of the armature vibrates between main poles 4 of opposite polarity, and the limbs 15 sweep across additional poles of opposite polarity. In the construction shown in Fig. 11, the armature 9 is of Y-shape, and its two limbs 30, 31 vibrate towards and away from poles N, N<1>, and across poles S, S<1>. A damping pad 32 of rubber &c. arranged between the limbs 30, 31 is adjusted by a screw 33. In other modifications, Figs. 12-14 (not shown), similar branched armatures are employed, in some cases with more than two limbs, and cooperating with poles differently arranged. Specification 349,146, [Group XXXVIII], also is referred to.

Title: Word logic circuit
IPC: G11C15/02
Filed: 1966-04-05
Abstract: 1,108,688. Associative-store. GENERAL PRECISION SYSTEMS Inc. 5 April, . 1966 [4 May, 1965], No. 15118/66. Heading G4C. [Also in Division H3] An associative store is provided with a simplified circuit for controlling the rewriting (or modifying) of the contents of addresses for which match signals are obtained. An associative store (a one-word cell 15 of which is shown in Fig. 1) comprises a non-magnetic wire 15a coated with a thin magnetic film 15b to which a number of digit lines 17-19 are linked. Digits are written by the coincidence of a current in one of lines 17-19 (produced by digit write driver 20) with a current in wire 15a, the currents of opposite polarity for writing the binary digits 1 and 0 respectively being produced in this wire by write drivers 30 and 36 coupled to magnetic cores 11, 12 which may be cleared by clear driver 28 and through which the wire 15a passes. The word to be compared with the contents of the store is stored in address register 22 and by means of interrogate driver 20 produces currents in lines 17-19 having polarities related to the bits in register 22. In those words 15 where there is a mis-match a current is induced in wire 15a, thereby actuating sense amplifier 13 and setting previously cleared cores 11, 12 so that subsequent actuation of drivers 30, 36 has no effect. In those words 15 where there is a match, no current is induced, amplifier 13 is not actuated, the cores 11, 12 remain cleared and on subsequent sequential operation of the drivers 30, 36 respectively the one's and zero's are re-written into the stores 15. A matrix of word stores is illustrated in Fig. 2 (not shown) and in a modified but functionally equivalent embodiment (Fig. 3, not shown) one core only is used, but the sense amplifier 13 is latchable.

Title: Discharge quantity control apparatus
IPC: F16K21/16
Filed: 1973-03-30
Abstract: 1422005 Valves ITT INDUSTRIES Inc 30 March 1973 [1 April 1972] 15377/73 Heading F2V Apparatus for controlling the quantity of liquid discharged from an outlet 24, Fig. 1, comprises a flowmeter 10 of the rotary type, flow quantity selector means 11, 13, a valve 21, and means for coupling the selector means with the flowmeter so that the valve is automatically closed after the selected flow quantity has been discharged. After selecting the flow quantity by angular adjustment of knob 11 with respect to fixed scale 12, the knob and valve assembly 11, 21 is moved axially from the valve-closed position, Fig. 3 (not shown), into the valve-open position shown, whereby spring-loaded pin 16 rides over the frusto-conical portion of a flange 17 on an element 13 and enters a groove 19 thereby retaining the assembly in the valveopen position wherein gear-wheel 18b on the element 13 meshes with output gear-wheel 18 of the flowmeter. Thus the element 13 is rotated by the flowmeter when the valve is open. The flange 17 has therein a transverse groove (20) which after rotation of the element through an angle corresponding to the angular setting of knob 11, moves into alignment with the pin 16 thereby enabling a spring 15 to force the assembly to return to the valve-closed position. A damper 34, 35 provides smooth return movement. The element 13 may have a stop (25) screwed into one of several angularly spaced holes in its periphery for applications where quick adjustment of knob 11 regularly to the same setting is needed, e.g. in hospitals for filling baths. Removal of the element 13 for altering the position of the stop is possible after removal of cap 32 and ring clip 27. The valve may be closed prematurely by rotating a knob 22 to retract the pin 16 against the action of its spring 30. The apparatus may be associated with a mixer device 2 having hot and cold water connections and a graduated handle 3. The valve may be located downstream of the flowmeter.

Abstract: 873,266. Printing machines. ALLER PRESS A. S. May 14, 1958 [July 4, 1957], No. 15469/58. Class 100(2) A damping apparatus for an offset printing machine comprises a damping roller to transfer the wetting liquid directly or indirectly to the plate cylinder, and a supply roller which dips into a bath of the liquid and which is arranged to be rotated at such a speed that it throws the liquid centrifugally against the damping roller, the supply roller not being in contact with the damping roller. The supply roller 14 is contained in a box 22 of which the lower part 18 constitutes a container for the liquid 16. A perforated plate 20 is fastened to the periphery of the roller 14 so that when the roller is rotated in an anticlockwise direction, the drive being taken through a variable speed gear, it picks up liquid 16 and throws it outwards by centrifugal force. Some of the liquid so thrown passes out of the box 22 through a slot 24 and moistens the surface of the damping roller 12 which rotates in contact with the plate cylinder 10. The liquid which does not pass through the slot 24 runs down the sides of the box back into the container 18. One edge of the slot 24 is constituted by a number of shutters 26 arranged side-by-side and individually adjustable, so as to widen or narrow the slot, by means of screws such as 28. One end of the container 18 is defined by a low wall 44 which the liquid 16 can overflow, the liquid being fed into the container by a pipe 50 having a valve 52 and which discharges the liquid between two plates 54. The box 22 is pivoted at 34 and its inclination can be varied by means of a screw 38; in this way the level of the liquid 16 in relation to the roller 14 can be regulated. A fixed tray 46 having an outlet 48 is disposed beneath the box 22 and receives liquid which flows over the wall 44 or is otherwise spilled from the apparatus. A wooden lath 56 positioned below the surface of the liquid 16 keeps the surface of the liquid calm.

Title: Production of crimped tows of polyacrylonitrile filamentary material
IPC: D02G1/12
Filed: 1956-05-18
Abstract: In a continuous process for producing a crimped tow of filaments of polyacrylonitrile containing a major portion, e.g. 75 per cent by weight, of acrylonitrile combined in the polymer molecule, a dry uncrimped tow is wetted (100-700 per cent by weight of water) and heated by an aqueous fluid at a temperature of 155-205 DEG  F. and is continuously fed under uniform tension (0.005-0.5 grams per denier) to and crimped within a zone which is within said temperature range. The hot crimped tow is passed, while it is relaxed, to and through a separate cooling zone in which it is cooled to a temperature below 120 DEG  F. to set the crimp.  The aqueous fluid may contain an "effect" agent, e.g. an anti-static material containing a low viscosity oil or a lubricant.  The tow fed to the crimping zone may have a residual shrinkage of 0-3 per cent or may be pretreated to remove such shrinkage by continuous passage, <FORM:0809039/IV (c)/1> in a relaxed state, through a liquid at a temperature of 210-230 DEG F. with a dwell therein of 5 seconds to 30 minutes and tensioning the tow to align the filaments thereof.  Cooling may be effected by passage through air at "room" temperature or exposure to blasts, sprays or a circulation of cooling fluid during which the tow may be supported on a porous conveyer.  As shown in Fig. 1, tow 10 is led from a tunnel or apron dryer 12 by an apron 14 and passed continuously through a shrinkage removal zone provided by a J-box 16 which may have, on each side at 24, alternately operating liquid sprays which deposit the tow in a spiral form 26 which is subjected, in a jacketed section 28, to a hot fluid, e.g. steam or non-solvents (in relation to the filament material) such as ethylene glycol, diethylene glycol, ethylene glycol monoethyl ether, glycerol, propylene glycol.  Tow then receives the aqueous fluid treatment at a temperature of 155 DEG  to 205 DEG  F. in a device 60 which may be spray means or a bath in which the tow, guided by rollers, is repeatedly immersed.  Tow 76, continuously crimped in a "nip-rolls and stuffer-box" apparatus and discharged on to a conveyer 80 is cooled in a J-box 84.  If water is the coolant, it is removed from the tow, as by a squeeze roll, and the tow is dried or stapled, dried and opened.  If dry tow is to be freed of residual shrinkage, it may be first wetted with water, e.g. by a spray, trough, tube or wiper (not shown) to facilitate subsequent handling.
